Answer: Bottom-Right corner
The points are (-5,6) (-5,-6) (4,-6)
-----------------------------------------
Explanation:
What you do is go through each of the answer choices, plot the points, and see which give you a right triangle. A right triangle has one 90 degree angle.
The upper-left choice leads to an obtuse triangle, so we can cross that off the list. It turns out that the other choices lead to right triangles.
The upper-right choice has a hypotenuse of roughly 11.18, so that's also eliminated
The bottom-left choice has a hypotenuse of 10.82, which means we cross that off the list
The bottom-right choice has a hypotenuse of 15, so we found the answer
Note: you use the distance formula to find the length of the hypotenuse. The distance formula is
d = sqrt((x1-x2)^2+(y1-y2)^2)
The equation is y=-5x + 20, x being the hours that go by after 5pm.
Answer: 318 = 121
Step-by-step explanation:
73 and the angle to solve for add to 180 because they are supplementary.
180 - 73 = 107.
5x + 2 = 107.
5x = 105.
5x/5 = 105/5
x = 21
